Electrical Problems, I have a short somewhere, Possible Solutions Options

[Cutrara]

Since Monday, a short somewhere in my wiring has been draining my battery (No, it's not the battery or alternator, I had them both checked) I took my car to get inspection/emissions and had them check it. He said the alarm was draining more power than it should. I pulled the alarm brain and disconnected the constant 12+, and ground wires from the alarm harness, and it's still draining. I have work all weekend and school all next week. I've designed a battery kill switch to cut off the battery as a temporary solution until I can diagnose the wiring problem over Christmas break.

Here is the kill switch I've designed:


Does this look OK for the application I'm using it for?
Would you improve anything?
Do you think something is shorting out?
Where do you think the short is?

Thanks,
Alex Cutrara

Ok i'm an installer for car stereo shop, I've seen some dumb installer put the start disable relay on the constant so it drain the battery every time the alarm is armed, you have to make sure it's connected to ignition. also try running a multimeter in series to read amp draw between different fuses, check to make sure alternator wire not touching ground (had many people have that prob). also you wired the relay up correctly you just need to find something like a 100 amp relay most stereo shops only have 30-40 amp. Hope that helps

P.S. make sure battery is still good everytime it drains all the way it cuts battery life in half.
